What to I need to make Irish Chocolate Cupcakes?
Here’s a list of everything you’ll need to make a fabulous batch of Irish Chocolate Cupcakes:
- Guinness beer
- Dutch cocoa
- Irish butter
- All purpose flour
- Sugar
- Baking soda
- Celtic sea salt
- Ground flaxseed
- Hot water
- Sour cream (or Greek yoghurt)
- Dark chocolate chips
- Heavy cream
- Irish whiskey
- Bourbon cream
- Powdered sugar

Why Dutch cocoa?
There are two main types of cocoa: natural and Dutch. In general, anything “natural” tends to have a better connotation, but in this case, one is not necessarily superior. Dutch cocoa is alkalized to reduce the acidity and is darker brown. Natural cocoa has not been processed with alkali and is the standard cocoa most commonly found at the grocery store.
Since natural cocoa is acidic, it pairs well with baking soda which neutralizes it. This chemical reaction between the two helps with the leavening process . Since Dutch cocoa’s pH is neutral, it pairs well with baking powder (also neutral) or with less baking soda. You can read more about the different types of cocoa here.
How do I make Irish Chocolate Cupcakes?
Guinness Cupcakes
Preheat oven to 350°F and line two muffin pans with 24 cupcake liners. Heat a small saucepan on medium-low heat and add the beer and two sticks of butter. As the butter melts, whisk the two together. Then add the Dutch cocoa and whisk until combined with the beer and butter. When smooth, remove from heat.
In a small bowl, whisk two tablespoons of flaxseed with six tablespoons of hot water. Let stand five minutes. This is the equivalent of two eggs. Then whisk the flour, sugar, baking soda, and salt together in a large bowl and set aside. Then pour the flax mixture into the bowl of stand mixer fitted with a paddle attachment and add the sour cream. Beat on medium speed until combined. Full fat Greek yoghurt may be used in place of sour cream.

Turn mixer to low and add the beer mixture. Use a spatula to scrape the sides and bottom of bowl to make sure everything is evenly mixed together. With the mixer still on low, gradually add the flour mixture. Be sure to only mix until the batter comes together–do not overmix. Alternatively, you could stir in the dry ingredients by hand to prevent overmixing.
Remove the bowl from the stand and fill each cupcake liner two-thirds full with batter. Bake for 17 minutes or until a toothpick inserted in the center comes out clean. Then, let the cupcakes cool for five to ten minutes before transferring to a cooling rack. Let cool completely before filling and frosting!

Irish Whiskey Ganache
While the cupcakes finish cooling, make the ganache. Start by placing the dark chocolate chips in a heat safe bowl. Pour the cream into a small saucepan on medium-low heat and add the butter.
When the butter melts and the cream begins to simmer, remove from heat and stir in the bourbon cream and whiskey. Pour the cream mixture over the chocolate chips and let stand for five minutes. Then use a fork or small whisk the stir the chocolate and cream until it is smooth and combined.

To make space for the filling, press the bottom of a medium sized piping tip into the center of each cupcake, going down about halfway. Then use the tip to scoop out the center of the cupcake. Save the cupcake centers for later.

Spoon ganache into the center of each cupcake, filling the entire hole. Then cover the ganache with the pieces of cake that were removed.

Bourbon Cream Frosting
Place the butter in the bowl of a stand mixer fitted with the whisk attachment and beat on medium speed for about 30 seconds. Turn the mixer to low and add the sugar and bourbon cream. As the frosting comes together, gradually increase the speed. (If you start too fast, you’ll end up with powdered sugar all over the kitchen!) Beat until it is light and fluffy.
The ideal frosting should hold it’s shape without being too dry. If the frosting is too runny, add more powdered sugar and if it is dry/crumbly, add a touch more bourbon cream. If you prefer not to have alcohol in the frosting, use heavy cream or half and half instead of bourbon cream.

To frost the cupcakes, fit a piping bag with medium sized tip such as Wilton #12, #21, or #1M. Place the bag in a tall glass and fold the sides of the bag over the rim. This will hold the bag and really reduce your mess whilst filling! Add frosting until the bag is about two-thirds full.
Remove the bag from the glass and squeeze the frosting to the tip until a little comes about. When the air is out of the bag, twist the top closed.
Starting in the center of the cupcake, squeeze the bag with even pressure and slowly make continuous circles of frosting working toward the outer edge. Repeat with the remaining cupcakes and refill the bag as needed. If you’re new to cake decorating, practice on a plate to get the hang of it first. Don’t worry if they don’t turn out perfectly–you can always scrape the frosting back into the bag and try again.

Serving and Storing
Irish Chocolate Cupcakes are best served at room temperature for optimal flavour and texture. If you are making them a day or two in advance, store them in the refrigerator in an airtight container and bring them to room temperature before serving. For longer term storage, they may be kept in the freezer.

Can I make a cake instead?
Yes! These Irish Chocolate Cupcakes can certainly be made into a cake! One batch will make two 8-inch cake layers. They will take about twice as long to bake at the same temperature. When a toothpick inserted in the center comes out clean, they are ready. When the cakes are totally cool, spread a thin layer of frosting between the cakes before adding a layer of ganache. Then use the remaining frosting for the top and sides. Follow the recommendations above for serving and storage.
